  1. Hi, I've some question about the dopNet, and the memory performance: I currently query the memory used in the simulation in this way def memConsumed(): try: sim = hou.node("../.").simulation() return "%s" %(str(hou.DopSimulation.memoryUsage(sim)*0.000001)) except: return "NONE" sys.stderr.write("\nMEM CONSUMED : %s MB" %(memConsumed())) A) Is working but the memory usage is quite different off from the memoryGrowth on the performance profile, is this last on reliable for the dopNet? I'm looking some method to go more in deep, I saw every object have record of the memusage, but unfortunately this one is not the sum of every child dependency in the network, example: memmoryUsage(x) = 10000000000 SIM_Objcet > 100 SIM_SolverMulti > 150 SIM_SolverSop(01) > 75 GAS_SubStep > 5000 ... > 30 ... > 999999 SIM_SolverSop(02) > 350 It may have sense to check the "self memory consumed", but in a debug prospective this is not really efficient IMHO Is there anyway to have the memusage as a sum of the relative child? C) are there any record field to describe if any gas solver is multi thread or not? right now the only way that I've is tun a profile and check rolling over for each micro-solver. D) any way to read the time usage for each node? (without dealing with the infoTree, I was expecting sidefx putting a field in the basic record for that like memusage ) E) there is anyway to append the profile file .hperf frame by frame? right now I'm saving a profile by stubstep so far this is my output SIM TIME : 14.25 Frame MEM CONSUMED : 43.389147 MB TIME CONSUMED: 0:00:02.204154 s POINTS : 508702 --- SIMULATION DATA --- Object: staticobject1 |_ MEM USAGE : 0.000361 MB |_ DATA TYPE : SIM_Object Object: HELLO |_ MEM USAGE : 0.000561 MB |_ DATA TYPE : SIM_Object |_ surface FIELD: | |_ DIV SIZE : 0.01 | |_ VOXEL COUNT : 198476 | |_ SIZE : [0.58, 0.59, 0.58] | |_ SLICE : 0 | |_ MEM CONSUMED : 0.772624 MB |_ vel FIELD: | |_ MEM CONSUMED : 0.722936 MB |_ pressure FIELD: | |_ MEM CONSUMED : 0.003616 MB |_ collision FIELD: | |_ MEM CONSUMED : 0.003616 MB |_ collisionvel FIELD: | |_ MEM CONSUMED : 0.007688 MB |_ source FIELD: | |_ MEM CONSUMED : 0.0036 MB |_ viscosity FIELD: | |_ MEM CONSUMED : 0.0036 MB |_ stickvel FIELD: | |_ MEM CONSUMED : 0.007688 MB |_FORCES: |_ Gravity_gravity1 |_ MEM CONSUMED : 0.000584 MB ------------------------------------------------- Profiler stopped and archived Profiles saved: /xxxxx_20180904_10_51_19/14.25.hperf (note the field are a list of interested one) I still need to work to read the solver process and collect all the info to process a % print thanks, Simone.
  2. A couple of version about the whitewater in H PART A: cached out the whitewater, I have the 3 group foam spray and bubbles, to see in viewport the result as in the dop lvl I'm running this wrangler if (inpointgroup(0,'foam', @ptnum) == 1) { @Cd = {0,0,.5}; } if (inpointgroup(0,'bubbles', @ptnum) == 1) { @Cd = {.5,0,0}; } if (inpointgroup(0,'spray', @ptnum) == 1) { @Cd = {0,.5,0}; } folloved by a vop with lenght and fit to manage the luminance based on velocity, question 1) there are a faster way human friendly to have this result? 2) vex doesn't have elif statemnt? PART B: whitwater solver is an asset using pop Solver, anyone tried to switch it in Flip? just to have more kernel structure of the 'fluid'. - other sw are using flip also for whitewater . thanks S.
